We have a cone, standing horizontally. A fluid enters to cone from the larger cross-section and makes centrifugal movement. Fluid moves towards small cross-section. At the small cross-section part we have to separate some particles from the fluid by centrifugal force. I would like to know that will the separation be more efficient if we have a smaller or larger cross-section at the end? or for example, is a cylinder more efficient or not? And how can we prove that?

Thanks

Accepted Answer

The equation for radial acceleration is given by the equation - Radial Acceleration = v^2 /r

v = rotational speed x r

so the radial acceleration as a function of rotational speed

Radial acceleration = rotational speed ^ 2 x radius

As a result the fluid is going to move from the small end of the cone to the large end and not the way you have indicated unless you have a very big driving force.
